First, the process of meat drying

1, equal speed drying stage

After 5-6 hours,  the temperature of the Naisida high temperature dryer rises to 60 ° C within 2 hours after loading into the oven. The  aim is to make fresh salami reach the same internal and external temperature within 2 hours, long

The warming process is also a process of seasoning and fermentation of meat to control the meat does not change color,  does not change taste. After the preheating time,  adjust the temperature to 45-50℃ and the humidity in the range of 50-55%. This stage table

The surface moisture has been evaporated,  and the color has changed from the grayish white of the feed to a light red. This stage is the color turning period,  and then the sausage is taken out of the barn, the head and tail of the sausage are inverted and hung,  and the sausage is sent into the barn to enter the wax

the

The second drying process.

2, slow down drying stage

Last 15-18 hours, there are two hair color period and contraction setting period. In the second color period,  the temperature is controlled at 52-54℃ for 4-6 hours, the humidity is controlled by 45%,  and the sausage gradually changes from light red to red

Bright red,  and the casing is beginning to shrink. In order to prevent the formation of a hard shell on the surface of the casing,  after the color period, ventilation and cooling should be used to deal with it,  the drying dehumidifier should stop heating, and the wet outlet should be opened to discharge

Hot and humid air is added to cold air for dry noise, which can make the skin temperature of the sausage drop rapidly,  which is conducive to the migration of water from the water inside the anal intestine to the surface. Contraction  setting stage two contraction setting stage

Period, to last 11-12 hours, during this period the internal moisture content of sausage continues to reduce,  sausage significantly contracted, the appearance of uneven phenomenon, the overall situation has been determined,  in the contraction of the shape

Period, that is, the start of the contraction set for 5 to 6 hours,  in the use of half an hour of cold air cooling to alleviate the contradiction between surface water evaporation and  internal water migration, to the end of the contraction set to complete.

3, rapid drying stage

In this stage,  the determining factor restricting the drying speed is the temperature. In order to strengthen the drying speed,  the temperature is increased to 55-60 ℃, the drying time is controlled at 22-24 hours,  and the relative humidity is controlled

At around 35%, the final drying humidity of the sausage is controlled below 17%.

Second, the advantages of Nysta drying dehumidifier drying solution

(1) The automatic control system can choose the best drying temperature and humidity according to the process  requirements of different products, which completely solves the long drying time,  high temperature and high energy consumption existing in other drying methods

Many problems, with unparalleled desk characteristics.

(2) The use of high efficiency centrifugal fan, with strong wind, uniform air supply, low noise characteristics,  material drying uniform and fast.

(3) No deformation, no cracking, no discoloration, no deterioration, no oxidation, thorough drying,  good rehydration after drying, less loss of nutrients, long storage period, more effective protection

Color, aroma, taste, type and active composition of the dried substance.

(4) The unit is integrated design, and the pipeline and power supply can be used on site;  Easy to operate, after setting the parameters, you can achieve automatic control, high reliability.

(5) Less investment, quick effect, can be used to transform old kilns, garages, etc., and can be migrated,  save land area, etc., simple and convenient.
